The 60407 flat crevice tool fits 1.5" (38.1mm) necks over a hose cuff, so it’s also applicable in commercial environments. The 9.5" (241mm) crevice is flat across the bottom, which, coupled with its wider berth, makes for maximum pickup of tougher to deal with materials. Like all crevice tools, the 60647 features continuous airflow. This crevice is black in color, and molded from plastic.
